Experiment 1 Reporting the Activity Data of This PDC [1]
Indication Obesity
Efficacy Data Fat mass reduction rate
45%
Administration Time Once a day for 14 days
Administration Dosage 100 nmol kg-1
Evaluation Method GLP-1-MK-801 produced a vehicle-corrected reduction in body fat mass of 45%, accompanied by an 8% loss in lean mass.
MOA of PDC
Treatment with GLP-1-inactive MK-801 produced no additional weight loss efficacy relative to GLP-1 monotherapy (Fig. 2g-i), indicating that the pronounced weight loss induced by GLP-1-MK-801 is driven by concerted and site-directed pharmacological GLP-1 receptor agonism and NMDA receptor antagonism.
In Vivo Model DIO mice
Half life period 1.9 h
Experiment 2 Reporting the Activity Data of This PDC [1]
Indication Obesity
Efficacy Data Lean mass rate
8%
Administration Time Once a day for 14 days
Administration Dosage 100 nmol kg-1
Evaluation Method GLP-1-MK-801 produced a vehicle-corrected reduction in body fat mass of 45%, accompanied by an 8% loss in lean mass.
MOA of PDC
Treatment with GLP-1-inactive MK-801 produced no additional weight loss efficacy relative to GLP-1 monotherapy (Fig. 2g-i), indicating that the pronounced weight loss induced by GLP-1-MK-801 is driven by concerted and site-directed pharmacological GLP-1 receptor agonism and NMDA receptor antagonism.

Experiment 3 Reporting the Activity Data of This PDC [1]
Indication Obesity
Efficacy Data Vehicle-corrected weight loss rate
9.50%
Administration Time 1 dose
Administration Dosage 0.22 nmol
Evaluation Method This study revealed a superior vehicle-corrected weight loss of 9.5% in response to the GLP-1-MK-801 infusion relative to a weight loss of 4.5% after semaglutide infusion (Fig. 4b).
MOA of PDC
Treatment with GLP-1-inactive MK-801 produced no additional weight loss efficacy relative to GLP-1 monotherapy (Fig. 2g-i), indicating that the pronounced weight loss induced by GLP-1-MK-801 is driven by concerted and site-directed pharmacological GLP-1 receptor agonism and NMDA receptor antagonism.
In Vivo Model High-fat high-sucrose-fed mice
Half life period 1.9 h
Experiment 4 Reporting the Activity Data of This PDC [1]
Indication Obesity
Efficacy Data Vehicle-corrected weight loss rate
15.20%
Administration Time Once a day for 9 days
Administration Dosage 100 nmol kg-1
Evaluation Method We observed a pronounced vehicle-corrected weight loss of 15.2% in the group treated with GLP-1-MK-801 compared with 3.5% in the group treated with the parent GLP-1 analogue after 9days of treatment, underscoring that the weight-lowering efficacy of the conjugate is intact in the absence of functional MC4R signalling (Fig. 3l,m).
MOA of PDC
Treatment with GLP-1-inactive MK-801 produced no additional weight loss efficacy relative to GLP-1 monotherapy (Fig. 2g-i), indicating that the pronounced weight loss induced by GLP-1-MK-801 is driven by concerted and site-directed pharmacological GLP-1 receptor agonism and NMDA receptor antagonism.
In Vivo Model Mc4r-KO mice
Half life period 1.9 h
Experiment 5 Reporting the Activity Data of This PDC [1]
Indication Obesity
Efficacy Data Vehicle-corrected weight loss rate
23.20%
Administration Time Once a day for 14 days
Administration Dosage 100 nmol kg-1
Evaluation Method Over a 14-day treatment period, GLP-1-MK-801 synergistically lowered body weight compared with the dose-matched monotherapies and produced a vehicle-corrected weight loss of 23.2%.
MOA of PDC
Treatment with GLP-1-inactive MK-801 produced no additional weight loss efficacy relative to GLP-1 monotherapy (Fig. 2g-i), indicating that the pronounced weight loss induced by GLP-1-MK-801 is driven by concerted and site-directed pharmacological GLP-1 receptor agonism and NMDA receptor antagonism.
